Title: Method for manufacturing semiconductor device
Inventor: TAKEUCHI KIYOSHI
IPC: H01L27/092
Filed: 2001-07-17
Abstract: PROBLEM TO BE SOLVED: To manufacture an integrated circuit constituted of a plurality of kinds of transistors having different threshold values at a low cost without deteriorating transistor characteristic. SOLUTION: In the case of resist formation for channel implantation, a resist is opened perfectly in a transistor whose threshold value is made high, and the resist is formed to cover at least the whole region to be a channel of a transistor, in a transistor whose threshold value is made low. After a gate electrode is formed, impurities are introduced to a part under a gate by an oblique ion implantation (pocket implantation). By covering regions A, B of n-type FETs with resist, a pocket impurity region 6' and a shallow source/ drain region 7' of a p-type FET are formed. After the integrated circuit is completed, p-type impurity concentration is low in a low impurity concentration region 4. As a result, a threshold value of the n-type FET in the region B is lower than that of the n-type FET in the region A.

Abstract: PROBLEM TO BE SOLVED: To provide a water tank, in which smudge or standing water is prevented from generating on the bottom face of the tank at the time of replenishment of water in a wet air-cleaner provided with the tank. SOLUTION: Inclination is made in the bottom face of the water tank 5 in the lateral and depth directions of the tank. A drain outlet 15 is formed in the deepest part of the tank.
